interesting tail pipe you have there..

 

ah you likey mi tailpipe eh?





it was tucked up hidden behind the factory bumper...then the Sawtooth and CBI came in and you could see it again..been wanting to chop it off or move it up more..

 

is it bad that i am looking forward to beating on my truck with a BFH today?

 

Looks like you have this setup pretty dialed in. Which shackles would you recommend for me to lower my rear end a little bit? These defined extended length ones are too long and I am a little too ass high for my liking.

 

haha, have fun!

 

i went from the 1" xj shackles to the stock length defined shackles and i like how that turned out...

i was lucky to have 2 sets of ATO mounts which allowed me to move my upper mount back...

the first set was too far back for the dakar leaf packs, so he sent me a new one which moved it forward to compensate for the shorter leafs..

the Toytec BOSS leafs are longer than the Dakars which required me to move my upper mount back to keep the stock length shackles in there..the XJ shackles helped to fill that gap with the more forward mounted ATO, but i wasn't getting full motion, so it was a waste..

so if you have ext. length shackles now, with good angles at ride height, you'll need to get a new upper mount, pushing the mounting point toward the rear of the truck so you can run shorter shackles..

been a while since i've seen your angles...

does your shackle drop straight down on full droop? are you closer to a 40-45* at ride?

 

you can also look into XJ stock length shackle options if you wanted to play with some cheaper shackles while you dial things in

i believe the ext. length defined is equivalent to the 1" lift XJ shackle

 

I would love to get a set of the stock length defined ones but $$ that I don't have comes into play then...

If I were to change the mounts that would be a bunch of grinding and re welding I think which wouldn't be necessary.

I haven't had a chance to play with the setup and look at full droop but here is the ride height with ext length shackles

So I would be looking at the no lift XJ shackles for temporary use?

 

my concern would be the ride height angle if you went to the stock length without moving the upper mount.

the spring will push the shackle back and ride at a flatter angle...i'm no expert, but from what i've read, you want to aim for the 40-45* ride height and vertical on full droop

 

i still have my factory shackle if you don't have yours

 

this is the 1" i went with,

$105 Warrior 1" Lift Shackle - 147

if i wanted to stay with the setup, i was going to throw down for a set of these greaseable shackles,

$151 Skyjacker Greaseable Rear Shackles - SH130

i have the warrior xj shackles still too if you want to toy around with those as well

 

Thanks Bob. I think the ext length I have on there now are going to be fine, I just dont like the huge rake is all. I guess it will go away at least a little bit when I get a bedrack and rear bumper though...

I will check and get back to you, might take you up on this

Thanks again

 

Again I would love to, next time I see you or am able to make it down to your area Ill let you know.

 

^this guy understands the headaches of leaf spring tuning

change one thing, 3 more things need to be changed

 

which is different than what the link i posted above says..



but i had the same mindset that you stated..the further forward the upper mount goes and flatten that angle, the softer the spring rate...while more near 90 the stiffer the spring rate

 

if you flatten the spring out, you get more into the stiffer compression rates in the progression...

on a scale of 1-10, 10 being further along the compression cycle and stiffer in the progressive spring rates..

a 90* to the plane stated in the picture above would be in the 5 range...further you flatten the spring, you move it along the compression cycle in the 5-10 ranges

 

makes sense, but how many shackle setups do u think actually function "correctly". meaning the angle of the shackle and spring length?

so with that said^ what number would u assign your leafsprings Bob? since the they are at negative arch at ride height? lol
